The world’s leading global companies excel because of world-class procurement organizations. Procurement contributes to the bottom- and top-line by operating atnearly 20 per cent lower costs and by securing profit margins up to 22 per cent higher than the average. The present dissertation addresses this deficiency by takinga collective creativity perspective on value creation in procurement. This dissertation investigates whether team climates conducive of creativity facilitate the performance of (cross-functional)sourcing teams and buyer-supplier co-innovation teams. The dissertation contributes to building a theoretical perspective for collective and creative problem-solving in the procurement and supply chainmanagement context. Concrete managerial recommendations for CEOs, CPOs and team members as to how collective creativity can contribute to bottom- and top-line results are provided.
